I am a postdoctoral associate in the flexLab (Flexible Structures Laboratory) at Ecole Polytechnique Fédérale de Lausanne (EPFL), currently working on the mechanics of elastic knots.

I performed my Ph.D. at Sorbonne Université working at the ∂'Alembert Institute on elasto-capillary interactions between elastic fibers and liquid drops.

Research Interests I thank the Agence Nationale de la Recherche (ANR-14-CE07-0023-01) for funding my PhD. thesis.
